Question

What is the difference of Inhibitory postsynaptic potential vs antagonist?

In: Biology

Answer 1

Excitatory post synaptic potentials make the neuron more likely to fire an action potential

Inhibitory post synaptic potentials make the neuron less likely to fire an action potential

EPSPs and IPSPs are weighed against each other to decide if a neuron fires or not.

An antagonist blocks the receptors on the neuron, making it so neither IPSPs or EPSPs can happen because the excitatory and inhibitory receptors are blocked

IPSPs try to stop the neuron from firing if there are more of them than EPSPs. Antagonists block excitation and inhibition from happening so there is no potential at all. There is just nothing, excitatory or inhibitory
